Annual outage 2016 to begin at Fortum’s Loviisa nuclear power plant

The annual refuelling and maintenance outage of Fortum’s nuclear power plant’s Unit 1 in Loviisa, Finland, begins on Sunday, 7 August.

Followed by the servicing of Unit 2. This year Unit 1 will undergo the extensive inspection outage performed every four years and Unit 2 is scheduled for a so-called short refuelling outage. The entire outage procedure is estimated to be completed in eight weeks.

In addition to the normal periodic maintenance tasks and refuelling, the most significant work on both units this year is the modernisation of high-pressure turbines and replacement of main transformer and generator breaker. At Loviisa Unit 1, reheaters and safety valves in the intial steam line will be replaced. At Unit 2, the generator’s rotor will be replaced and major overhaul of stator conducted. During the outage, one quarter of the fuel will be replaced.

«The turbine modernisation is among the most significant investment projects in the Loviisa power plant’s history and part of the continuous improvement of the plant. The investment ensures reliable electricity production of the plant units to the end of their lifetime. The modernisation will significantly improve the efficiency of the turbine plant’s electricity production without increasing the reactor’s thermal output,” says Timo Eurasto, Manager of Loviisa power plant’s Operations unit. Because the modernisation will target only the turbines, it does not impact the reactor plant or nuclear safety.

A total of 950 external contractors are involved in the Loviisa power plant’s annual outage and ongoing modernisation projects. There are approximately 500 Fortum employees and some 100 permanent contractors working at the Loviisa power plant.
